Rollup merge of #146732 - durin42:llvm-22-less-assumes, r=nikic
tests: relax expectations after llvm change 902ddda120a5
LLVM 22 is able to drop assumes that seem to not help further optimizations, which actually seems to dramatically _help_ further optimizations in some of our small test cases.
I'm a little unclear how to fix the last failure, in `tests/codegen-llvm/issues/issue-122600-ptr-discriminant-update.rs`:
```
-; Function Attrs: mustprogress nofree norecurse nosync nounwind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable
+; Function Attrs: mustprogress nofree norecurse nosync nounwind nonlazybind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable
define void ``@update(ptr`` noundef captures(none) %s) unnamed_addr #0 {
start:
- %_3.sroa.0.0.copyload = load i8, ptr %s, align 1
- %0 = trunc nuw i8 %_3.sroa.0.0.copyload to i1
- %1 = xor i1 %0, true
- tail call void ``@llvm.assume(i1`` %1)
store i8 1, ptr %s, align 1
ret void
}
```
I'm just not conversant enough in LLVM IR to follow the changes here.
